In this paper, we describe an n-gram approach to automatically assess essay quality in student writing. Underlying this approach is the development of n-gram indices that examine rhetorical, syntactic, grammatical, and cohesion features of paragraph types (introduction, body, and conclusion paragraphs) and entire essays. For this study, we developed over 300 n-gram indices and assessed their po...
for determination of grazing capacity, information of forage quality is essential which is influenced by various factors. the main objective of this research was investigation on effects of species, phenological stages, and life form on values of forage quality indices of six range species. species were two grasses (bromus tomentellus and dactylis glomerata), two forbs (ferula ovina and coronil...
We consider how to construct summary indices (e.g., Quality of Life indices) for a social unit (e.g., cities, states, nations) that will be endorsed by a majority of its citizens. We assume that many social indicators are available to describe the social unit, but that individuals disagree about the relative weights to be assigned to each social indicator. The summary index that maximizes agree...
